, 1 1 i My inventionrefers to tractor matic tires, the, same being provided .with Vmeans for removably securing said shoes to a :pneumatic: tire, whereby a pluralityofthe shoes may beat-H tached to the tire without jacking up a wheel:

The specific object of my invention is to provide with the, above and other' :objects in View,r

which will appear as the description proceeds, the invention'resides -in thejnovel construction, combination and arrangement of parts,l substantially as hereinafter described, and more particularly defined by the appended claim, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim. f v

In the accompanying drawings is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.

In the drawings,

Figure 1 represents a side elevation of a pneumatic tire wheel and associated shoes having a cinch bar connected embodying the features of my invention.

Figure 2, a similar view looking towards the inner face of the wheel.

Figure 3, a cross section of the wheel, the section being indicated by line 3-3 `of Figures 1 and 2.

Figure 4, a similar fragmentary cross sectional view, the section being indicated byline 4 4 of Figure 2, and

Figure 5, a fragmentary elevation of a modification illustrating the inner face of the Wheel having va modified form of shoe anchor attaching means.

Referring by characters to the drawings, A indicates a standard metallic webbed wheel and associated rim. Mounted. upon the rim is a standard pneumatic tire B.

The web A has secured thereto a pair of' straps shoes for rneu- 'will ntfengas'e t' of the tire, `whereby nderqrdinarypopditions it "d when theshpese'r in use. `Howeve inmso A manently secure the anchor straps ,'ff or"the li-oop( to the web of the wheel, byweldin'g or othersuitl` able means: 'w i of Mounted upon the tire Ltread of fthe wheel, iis, a'L

series of traction shoesdyihaving depending stirrup ,ends lfi". f The inner stirrup, ends Water-gv minata with hooks,- 5., #on pivotally engaging; the hanger he@ 3, and the ,oilterfsaddle 41* ,terminateswith a seriesof hooks jf'; The vouterstirruped ends of the traction'shoesare frictionally secured;

to the tire, by. cinch ba'rs'f, whichfcinchbars 'are preferably formed frrh "a" stretch of wirefflded upon itself `to developalink 1, at one end and* the opposite ends of thewire are bowed' outwardly to form pivot toes 8, as -best indicated in Figures 1and3ofthedrawings; 1

Hingedly mounted upon i the cinchbartoes 8 is a latch lever 9, the same being formedinl u I, which-straps -forconvenience are removably secured -to the web by bolts- 2-. The opposite -ends shape throughout itsvlength, whereby it may be conveniently nested about the cinch ba rwh en said latch is in its closedand locked p'ositicn. The side walls of the `latch lever are provided with apertures, for pivotally engaging 4the toes r8r of the cinch bar and at apredetermined distance below the above mentioned pivot connection, the side walls are providedwith apertures,`for1the' reception of the iends of a wire link I 0. y -r As shown in Figure `5'oi Ythe drawingsin some instances I may substitutethe continuous anchor hoop 3, for a series of wire loops Il, which Wire loops may be welded to the rim of thewlieel,l or

the same may be pivoted thereto in any suitable manner, whereby the saine can be removed, when the tractor shoes are notin use. These loops Il have pivoted thereto any type offshoed and a suitable number of said loops may be employed, depending upon vthe road or groundconditions, where tractors or the like are employed.` i

From the foregoing description in order to mount a series of tractor shoes upon a wheel, the hooked ends 5 of said shoes are first `pivotally mounted upon the hoop 3, -it belngbunderstood that a pair of such shoes are disposed opposite' each other. For example, as shown in IE'i'gfure l1 of the drawings; four`=shoes are'illustrated as a However,` insome stances Vone set of these shoes may be employed. A s-'bestindicated in'rFigure 1 of the'dl'ivv'i'ngs!'lv possible requirement.

a cinchbar 6 is adjusted to a pairiof the stirrup hooks l and thereafter theV cinch bar is swung After the coupling connection is effected, the

latch lever is swung downwardly to the position, as indicated in full lines, Figure 3, whereby the pivot ends of the wire link will swing inwardly, beyond the latch lever pivotm thus tightlydrawing the entire cinch bar unit together, whereby the pair of traction shoes are frictionally and firmly locked upon the tread of the wheel and said latch lever in this locked position is nested about the wire stretches of the cinch bar 6. It should further b e understood that for convenience in avoiding the hub elements of the wheel, the cinch bars are slightly bowed outward from end to end, whereby a pair of cinch bars are folded, one over the other, at the axis of the 20 wheel.

I claim:

In a wheel having a pneumatic tire mounted thereon a pair attraction shoes itted over the tire having depending stirrup ends secured to the wheel, a cinch bar for the pair of shoes, compris- 5 ing a wire strand folded upon itself to form a link at one end and a pair of pivot toes at the other end, a latch lever pivotally mounted upon the toes, and a. wire link pivoted to the latch lever, the ends of the cinch bar being adapted to fric- 10 tionally corinne the tractor shoes upon a tire.
